Bakflip mx4

Just got the F150 primarily for tailgating and wanted a cover to protect and secure coolers ,grill,tents etc during the trip to and from eve to. Neighbors has the G2 cover and is very happy with it and lead me to Bakflip. After research I went with the MX4 due to the 5yr warranty. Rec'd few quickly after ordering and installation was very easy after reading the instructions ND the countless install videos. I did get water leakage and placed a call into Bakflip and with supplied pictures feemed to be from manufacturing not installation. Bakflip sending new cover . Need to install and test
